Check Digit Verification of cas no

The CAS Registry Mumber 844486-60-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,4,8 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 844486-60:
(8*8)+(7*4)+(6*4)+(5*4)+(4*8)+(3*6)+(2*6)+(1*0)=198
198 % 10 = 8
So 844486-60-8 is a valid CAS Registry Number.

Regioselective synthesis of peptidic derivatives and glycolamidic esters of Methotrexate

Castex, Cédric,Lalanne, Christophe,Mouchet, Patrick,Lemaire, Marc,Lahana, Roger

, p. 803 - 812 (2005)

Convenient methods for regioselective syntheses of Methotrexate peptidic conjugates are described. Solid phase synthesis for derivatives of Methotrexate containing an amide bond has been applied and showed higher efficiency than liquid phase synthesis. Synthetic pathways for regioselective preparation of Glycolamidic ester derivatives of Methotrexate were also developed using 4-amino-4-deoxy-N10-methylpteroic acid as starting material. These ester bonds were obtained either in solution or by using a combined liquid and solid phase synthesis.
